Authorities, Containers, Entities Authorities, Containers and Entities, Oh My SDS data model is based on this concept Provides flexible schema Easy to create data structures

Authorities, Containers and Entities, Oh My

SDS data model is based on this concept

Provides flexible schema

Easy to create data structures

Authorities, Containers, Entities Authorities Topmost level of the hierarchy anontypes-01 DNS name https://anontypes-01.data.database.windows.net/v1 Maps to specific data center Is a unit of geo-location

Authorities

Topmost level of the hierarchy

anontypes-01

DNS name

https://anontypes-01.data.database.windows.net/v1

Maps to specific data center

Is a unit of geo-location

Authorities, Containers, Entities Containers Each container has unique id associated Store the data contained in the application Cannot be in a different geo-located Authority Can contain homogeneous or heterogeneous data

Containers

Each container has unique id associated

Store the data contained in the application

Cannot be in a different geo-located Authority

Can contain homogeneous or heterogeneous data

Authorities, Containers, Entities Entities Actual bits of data stored in container Stores any number of user-defined properties/values Retrieved, added, updated, deleted Partial updates are not supported Entire entity is replaced in container when updated

Entities

Actual bits of data stored in container

Stores any number of user-defined properties/values

Retrieved, added, updated, deleted

Partial updates are not supported

Entire entity is replaced in container when updated

Homogenous/Heterogeneous Data Homogeneous data is similar to a database table, in which all entities are of the same kind Books container stores “book” entities Highly structured applications should use Heterogeneous data contains all types of entities MyOffice container stores “books”, “supplies”, “furniture” Allows for querying across all entities in parent container

Homogeneous data is similar to a database table, in which all entities are of the same kind

Books container stores “book” entities

Highly structured applications should use

Heterogeneous data contains all types of entities

MyOffice container stores “books”, “supplies”, “furniture”

Allows for querying across all entities in parent container

Flexible Entities Key concept of SDS XML fragment with one element per property value. Value restricted to simple scalar type of string String, binary, Boolean, decimal, datetime Fixed metadata properties – Id, Version, Kind Version. New version assigned with each update Kind. User-defined, identifying the entity type

Key concept of SDS

XML fragment with one element per property value.

String, binary, Boolean, decimal, datetime

Fixed metadata properties – Id, Version, Kind

Version. New version assigned with each update

Kind. User-defined, identifying the entity type

Anonymous Types A new podcasting website featuring the little known development geeks Site runs on a hosted server Data is hosted on SQL Data Services Leads to differences in how we work with data When using REST, return types are XML Need to use LINQ

A new podcasting website featuring the little known development geeks

Site runs on a hosted server

Data is hosted on SQL Data Services

Leads to differences in how we work with data

When using REST, return types are XML

Need to use LINQ

Differences to remember An Entity is like a property bag – keys/values Each Entity in a Container can have a different structure Different paradigm than when working with database tables There is no “primary key”, instead an “EntityID” User defined value

An Entity is like a property bag – keys/values

Each Entity in a Container can have a different structure

Different paradigm than when working with database tables

There is no “primary key”, instead an “EntityID”

Containers Can contain heterogeneous, homogeneous, or flexible entities For this project decided to have four Containers at_page at_podcast at_podcastdata at_guest

Administer text data

Upload and administer BLOB’s (podcasts)

Demo only shows uploading – not streaming down

Standard ASP.NET Membership, Roles, Authentication for Admin pages

Using REST POST (Insert, Create) PUT (Update) GET (Retrieve) DELETE (Delete)

Page Administration Insert, Save, Edit, Delete Page code creates XML passed to the class Methods SelectPages() SelectPage() InsertPage() UpdatePage() DeletePage() Make sure to HtmlEncode strings going in HTML chars will mess things up with validity of the XML

Insert, Save, Edit, Delete

Uploading PodCasts (BLOBs) Uploading of BLOBs is possible, but can only send the object, no other data Create two XML strings PodCast EntityId, Container, FilePath PodCastData Meta and other data about the PodCast EntityId,Title, RunTime, Guest, Publish Date, etc. Since two different containers, can have same EntityId

Uploading of BLOBs is possible, but can only send the object, no other data

Create two XML strings

PodCast

Meta and other data about the PodCast

EntityId,Title, RunTime, Guest, Publish Date, etc.

Since two different containers, can have same EntityId

Uploading PodCasts (BLOBs) Two step process First insert the Meta data Title, Guest, Description, etc. If successful, upload the PodCast
